14 lbs is where the whole UK weight system begins
I have built converters for years, and everything traces back to one line: 1 stone = 14 lbs, exactly. When you turn 10 stone into pounds (140 lbs) or 200 lbs into stone (14 stone 4 pounds), the maths always passes through 14. That makes 14 lbs to kg more than a routine conversion. It is the anchor number, the one worth memorising as 6.35 kg.
